Questioning Techniques
Hide the box in a bag and ask the children to identify the object inside.
They can ask any question that you can answer by saying: yes/no.
Suppose we had a magic box of Alpha-Bits and the letters could jump out
of the box and form words that would answer any question you may ask.
Write down l0 questions you'd like to ask the cereal box.
Classify the questions: are they answerable by ...
Pass out cereal to each class member. Have them push l0 letters to one side,
l0 to the other and eat the rest. Make a histogram/bar graph of the vowels.
What % of the sample is each vowel ? Is this a representative sample ?
Try again with the other l0 letters. Are the percentages similar ?
How many letters are there in the box ?
Determine how many letters it takes to equal l / l00th of the mass of the box.
Extrapolate this datum.
Using the percentages gained from activity above, estimate the total
number of each vowel in the box.
Test your inference -- actually count them ... oops... better not eat any
before you do this part.
?
Don't forget the mother of the truck driver; the tax agent for the
company; the person who painted the white line on the highway; the
person who made the saw that cut the tree that was planted by a
person to make the paper to form the box.
The list is an endless invitation to creativity.
Find an example from the newspaper where some segment of society
did something that influences the livlihood of people "far away"
(either in distance or apparent relatedness)
What percent of the cereal is carbohydrates ?
Note: 28.35 grams = l oz; so if they say in a one ounce serving there
are 25 g of carbohydrates; that is --
88.2% [ 25g / 28.35g ].
9 / 28r / 95
